Metal laser cutting machines are specially designed for cutting and processing metal materials. Types of metal laser cutting machines are the main part of machinery and production all over the world. Based on the type of laser, these devices are mainly classified into three categories: crystal, CO2, and fiber.
How to operate all kinds of metal laser cutting machines
What are the types of metal laser cutting machines?
There are three different forms of lasers for cutting metals in industrial production. Each laser cutter has unique characteristics that distinguish them from the others. Laser cutting machines are differentiated based on the types of lasers used. As a result, the type of laser determines the type of substrate and the thickness of the metal. CO2 laser cutting machine CO2 laser cutting machines are made of CO2 gas and a mixture of other gases. They are formed like helium and nitrogen. This type of gas mixture is charged with an electrical discharge and then produces a laser beam. The wavelength of these cutters is 10.6 mm.
CO2 laser cutting is the most common and famous among all types of metal laser cutting machines due to its efficiency and cheaper price. These types of machines can generally cut thin sheets of aluminum and other metals. It is possible to increase the power of the CO2 beam by increasing the oxygen content, but this can be dangerous in the hands of inexperienced persons or with machines not suitable for such enhancements.
In order to cut metal, these machines must have at least 150 watts of power. and use the help of oxygen. Failure to observe precautions while working with this device can cause immediate lacerations, blindness, and burns. Also, due to the oxygen gas in this machine and incorrect contact with the gas tank, there will be a possibility of ignition or explosion.
✨ crystal laser cutting machine
Crystal lasers produce beams of yttrium orthovanadate doped with neodymium. The wavelength of these cuts is smaller compared to CO2 laser cuts. Therefore, these types of devices can cut thicker materials. There are two forms of crystal laser cutting: Nd:YAG crystals (neodymium-doped yttrium aluminum garnet) and Me:YVO (neodymium-doped yttrium orthovanadate) crystals. Both are extremely powerful cutters. However, these lasers are very expensive, but they will have almost half the lifetime of fiber lasers. One of the drawbacks of these cutters is the rapid wear of their parts due to their high power performance. ✨ Fiber laser cutting machine
This type of laser uses optical fibers. Special is amplified and magnified. The more common name of fiber laser cutting is solid state laser.
Among the significant advantages of this laser cutting, we can mention the cutting of reflective and conductive metals, three times efficiency compared to CO2 laser cutting, and the absence of moving parts. Although fiber laser cutters are very similar to crystal lasers, they are more efficient and require less maintenance.
Fiber lasers are many times more powerful than CO2 lasers. This means that, like CO2 lasers, they can cause burns and blindness. But even indirect exposure to lasers can cause damage. While working with these devices, you must use proper safety equipment and suitable laser chambers.
💥 Application of all types of metal laser cutting machine
In the metalworking industry, where industrial production plays a major role, many metallic materials, regardless of their hardness, can be cut without deformation. The thickness of industrial steel close to 20 mm can now be cut with advanced metal laser cutters. Of course, for highly reflective materials such as gold, silver, copper and aluminum alloys, which are good conductors of heat, laser cutting is difficult or even impossible. Some hard cutting materials can be cut with a pulsed wave laser beam. Types of metal laser cutting machines in sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, machinery, ships, metallurgical equipment, They are used in elevator, household appliances, tool processing, decoration, advertising, metal processing, etc. These machines are mainly used for cutting carbon steel, silicon steel, stainless steel, aluminum alloy, titanium alloy, galvanized sheet, aluminum zinc sheet, copper. and other metal materials are used.
